Hacking Jacket

Where can I buy replacement buttons for my beautiful coat piracy? They are silver, round with a horse head on? I saw some in the house of Derby or Robinsons but they are not as beautiful. My jacket is a jacket London Excel but I can not find online?

You can take the jacket with you and go to a sewing shop that has buttons, son, sewing, fabrics, etc. You can look in the section buttons to see if they have anything similar or identical to you are looking for.
